Field Portage Bags
Holds a 9”x12” tablet, has lots of pockets, and comes with a detachable shoulder strap. This is a good size tote to keep loaded and ready to go.
ArtBin's Sketch-Pac holds sketching and graphic arts tools such as pencils, pens, charcoals, erasers, and brushes. With two sides divided by a transparent layer, there's twice the storage space. Ideal for travelling.
Finally, attractive boxes large enough to store odd-sized papers and artwork! Or, in my case, old calendars I've saved.
